Viltis Chemo Hat Crochet Pattern

It’s hard to believe this is my 6th year taking part in the Crochet Cancer Challenge. For the past few years this challenge has taken on a whole new meaning and this year the Viltis Chemo Hat is no different. I chose bladder cancer again this year (read why below). The colors of the bladder cancer ribbon are yellow, blue, and purple.

If you haven’t heard of the Crochet Cancer Challenge here is a quick rundown. You receive a free pattern (the offer is for a limited time). In exchange for that pattern, you pledge to make at least 1 of that hat and donate it to cancer patients or a treatment center. The challenge runs all through October, which is cancer awareness month.


In January 2019 the cancer challenge turned personal for me when my husband was diagnosed with stage 4 Upper Tract Urothelial Carcinoma (UTUC), which is a rare form of bladder cancer.

Since that diagnosis he’s had surgery twice (once to remove his kidney and once to remove 14 lymph nodes in his abdomen), 3 rounds of chemotherapy, and is currently undergoing immunotherapy. If you’d like to read more of the story I wrote for last year’s challenge you can here.

Honestly, the last 3 years have been the hardest years of my adult life. What you don’t see is the mental tole that cancer takes on people, not just the physical (that comment is not to discount the physical). This is a journey I would never wish on even my worst enemy.

Viltis means “hope” in Lithuanian, which is where my husband’s grandparents were from. We need to hold onto hope. I wrote the following for the Hope Lives Chemo Hat that I made for the challenge in 2018, but I wanted to share again because so many people need to remember there are people out there struggling to keep their hope alive. Hopefully these hats will help just a bit.


Hope lives in those who have been diagnosed with cancer.

Hope lives in their loved ones.

Hope lives in every doctor fighting to find a cure.

Hope lives in every nurse who cares for their patients.

Hope lives in the hearts of every person who knows or loves someone fighting for a cure.

So, this year, I pray my hat can be a reminder to keep your hope alive and never give up.

  • Hat is worked from the top down.
  • Colors on striped sample were changed every row and carried up the inside. I actually deconstructed the cake to just use the 3 colors I wanted, which represented the Bladder Cancer ribbon. Feel free to let the yarn stripe itself, make your own color stripes, or use a solid color. 
  • The brim/border uses both the FPdc as well as the FPesc. The reason for this was that the FPdc was a bit too bulky for my liking with the sc on the last round, so it was intentional.

The Viltis Chemo Hat crochet pattern will be free from Oct. 13th – Oct. 20th using code CancerChallenge.

Please remember that if you download a copy of the hat pattern, you are pledging to make at least one hat from it to donate to a cancer patient or treatment center.
